- Department of Chemistry, Annamalai University, Annamalainasar-608 101 Manuscript received 19 January 1979, revised 18 June 1979, accepted 4 August 1979 The rates of ethylation of some mono and disubstituted sodium phenoxides with ethyl Iodide at 30° have been determined. The 3-methyl group in sodium 4-methoxy-3-metbyl-pheooxlde or the halogeno group in sodium 4-metboxy-3-halogeaophenoxide does not sterically inhibit the resonance Interaction of the methoxy group with the aromatic ring but enhances lt. The kinetic data obtained In the present study provides acidltional eyidence for the concept of steric enhancement of resonance.
